The present invention relates to a process for hydroxylation of a compound of formula (I) by reacting the compound of formula (I) with an oxidizing agent, in the presence of a titanium silicalite zeolite prepared by crystallization preceded by a maturing step. The present invention also relates to a titanium silicalite zeolite and to the process for preparing same.

A hydrocracking catalyst comprises an active cracking support. The active cracking support comprises a post-modified zeolite framework having zirconium atoms and titanium atoms substituting for aluminum atoms; wherein: a portion of the zirconium atom are substituted in the post-modified zeolite via 4-coordination; a portion of the zirconium atom are grafted to the post-modified zeolite via 5-coordination; and the titanium atoms are substituted in the post-modified zeolite framework via 4-coordination.

A catalyst composition includes a heterobimetallic zeolite characterized by a chabazite structure loaded with copper ions and at least one trivalent metal ion other than Al.sup.3+. The catalyst composition decreases NO.sub.x emissions in diesel exhaust and is suitable for operation in a catalytic converter.

The present invention relates to a process for the preparation of a zeolitic material comprising the steps of: (1) providing a mixture comprising one or more sources for YO.sub.2 and one or more alkenyltrialkylammonium cation R.sup.1R.sup.2R.sup.3R.sup.4N.sup.+-containing compounds as structure directing agent; and (2) crystallizing the mixture obtained in step (1) to obtain a zeolitic material; wherein Y is a tetravalent element, and wherein R.sup.1, R.sup.2, and R.sup.3 independently from one another stand for alkyl; and R.sup.4 stands for alkenyl, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.

A SCM-33 molecular sieve has a schematic chemical composition as shown in the formula SiO.sub.2.Math.1/x XO.sub.1.5.Math.m MO.sub.0.5, wherein X is a framework trivalent element, the Si/X molar ratio x is 5, M is a framework equilibrium cation, and the M/Si molar ratio is 0<m1. The molecular sieve is a novel molecular sieve with RTE topology and the molecular sieve requires short preparation time, involves a low synthesis cost and can be used as adsorbent or catalyst.

A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-116, is provided. SSZ-116 can be synthesized using 3-[(3,5-di-tert-butylphenyl)methyl]-1,2-dimethyl-1H-imidazolium cations as a structure directing agent. SSZ-116 may be used in organic compound conversion reactions and/or sorptive processes. This disclosure also relates to the structure directing agents used in the methods for making the SSZ-116 material as well as the synthesis method used to prepare such structure directing agents.
